| 7 | Use driver model for PCI. Driver model is the new method for |
| 8 | orgnising devices in U-Boot. For PCI, driver model keeps track of |
| 9 | available PCI devices, allows scanning of PCI buses and provides |
| 10 | device configuration support. |

| 16 | Support PCI on sandbox, as an emulated bus. This permits testing of |
| 17 | PCI feature such as bus scanning, device configuration and device |
| 18 | access. The available (emulated) devices are defined statically in |
| 19 | the device tree but the normal PCI scan technique is used to find |
| 20 | then. |

| 28 | 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports |
| 29 | with a total of 5 lanes. Some boards require this for Ethernet |
| 30 | support to work (e.g. beaver, jetson-tk1). |
